specific Embodiment approach 1

[0015] Specific embodiment one: A kind of method of preparing carboplatin hollow spheres with Haematococcus pluvialls as reducing template in this embodiment is carried out according to the following steps:

[0016] (1) Fixation of Haematococcus pluvialis: Collect Haematococcus pluvialls in the culture medium by filtration under reduced pressure, wash with distilled water and absolute ethanol under reduced pressure for 1-5 minutes, and then add to formaldehyde Soak in forest solution for 10 to 120 minutes, filter under reduced pressure and wash with distilled water under reduced pressure for 1 to 5 minutes to complete the fixation and purification of Haematococcus pluvialls, wherein the Haematococcus pluvialls used is red aflagellate quiescent cells;

[0017] (2) Preparation of platinum plating solution: add 5.0~25.0 g / L gluconic acid into a mixed solvent composed of deionized water and acetone, adjust the pH value to 8.0~12.0 with ammonia water, then add 0.1~5.0 g / L Platinum ...

specific Embodiment approach 2

[0021] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the volume percentage of acetone in the mixed solvent described in step (2) is 5-30%. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the platinum salt described in step (2) is tetraammine platinum chloride, tetraammine platinum nitrate, ammonium chloroplatinite or platinum chloride A kind of potassium acid. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a method for preparing carbon-platinum hollow spheres by using Haematococcus pluvialis as a reducing template. The invention relates to a method for preparing carbon-platinum hollow spheres by using Haematococcus pluvialis as a reducing template. The invention aims to solve the problems that the preparation method of the platinum particles with a high specific surface area is strict and complicated, the particle size is difficult to control, and the like. A method for preparing carboplatin hollow spheres using Haematococcus pluvialis as a reducing template: (1) fixation of Haematococcus pluvialls; (2) preparation of platinum-plating solution; (3) chemically breaking the wall of pluvialls Self-growth platinum on the surface of algae; (4) demoulding and hollowing, through the self-growth-removing template on the surface of the template reducing agent to obtain carbon-platinum hollow spheres with high specific surface area. A method for preparing carbon-platinum hollow spheres using Haematococcus pluvialis as a reducing template can prepare carbon-platinum hollow spheres with uniform particle size and high specific surface area in a simple and easy-to-operate manner, without adding a reducing agent during the preparation process, It is beneficial to the greening of the preparation process.

Description

technical field [0001] The invention belongs to the field of preparation of catalytic materials, and relates to a method for preparing carbon-platinum hollow spheres by using Haematococcus pluvialis as a reducing template agent. Background technique [0002] In the current era of shortage of energy resources, how to efficiently convert industrialized materials has become an important topic. The improvement of industrialized material conversion efficiency means the effective use of energy resources and will also provide strong support for the sustainable development of society. [0003] Efficient industrial material conversion is inseparable from efficient catalysts, and the preparation of efficient catalysts requires careful design of their materials, compositions, and structures. As an important noble metal material, platinum not only has good stability, but also shows unparalleled advantages in the field of catalysis, and has the highest catalytic activity in many catalyti...
